GreenlyWhen to plant garlic in New Zealand: 1 April – end of June
Garlic in New Zealand: plant from 1 April to the end of June; the window opens earliest in Wellington and closes latest in Christchurch (10 cities).
From a month before the first autumn frost, so the roots grow before winter, to the late-planting limit on each crop’s page (about two weeks before the ground freezes, by ten years of weather).
